The outside wall of the circularrefrigerator unit is designated by H and the inner wall of therefrigerator unit is shown by l2.

Spacing members 13' are located between the outer shell II and the innershell [2 of the circular refrigerator. These spacing members'are of aheight and width for proper alignment of the two shells of the food, icecube making and tical support of the food compartment andv notched at Iffor support of the ice cube making and frozen food compartments. Thespacing members may be suitably supported by braces located in thecompressor compartment.

The refrigerator food compartment l4 has a floor l5. Compressor coilsare shown. represented byv 6.

An ice cube making compartment is shown by I! and a frozen foodcompartment is designated as l8. The frozen food compartment has anadditional door I! with a handle 20, the door being hinged at l9.

The compressor compartment generally is designated by 2|.

In the food compartment II are a number of revolving shelves 22, whichshelves are supported by rollers generally designated as 23 and shown indetail by Figs. 3, 4, 5, 8, 9 and 10. These rollers are supported uponvertical strips 24, these strips having perforations 25 to permit up anddown adjustment of the rollers. In the floor of the food compartment isa gutter 26 having a drain pipe 21.

In the ice cube making compartment I! are trays 28 and back-stops 29 andeach tray has a cam lifter designated by 30.

In the frozen food compartment I8 is a suitably supported shaft 3|adapted to be rotated and upon this shaft are secured trays 32. In thisfrozen food compartment there is also a gutter 33 having a drain pipe34.

The compressor compartment 2| has a door 9, which door supportsa.vegetable bin 35. A handle for the door is designated by 36. In thecompressor compartment is a pan 3! in which are located by-pass coils38'from compressor to condenser. Both the aforementioned pipes, 21 and34, drain condensation into the pan 31 and by means of the by-pass coilsthe condensation is evaporated. v

Referring to the main door 5, this door is hun on top and bottom pivots39 and is self-closing by means of touch control 6, this doorcooperating with pivoted angle 40 in connection with spring bolt 4| andkeeper 42 located on refrigerator body. Also, there is a spring plunger43 adapted to afford easy'opening of the door. IAISO the refrigeratorcabinet has door jamb breaker strips or gaskets 44 attached thereto asdistinguished fromv the usual strips .secured to the door itself.

The door 9 which supports the vegetable bin 35 is hinged upon pivots 45.This door is self-closing through spring and toggle mechanism comprisinga tube 46 pivoted at 41 to bottom of frozen food compartment in which islocated a spring 48 pivoted to the toggle joint 49 and strap 50 which ispivotally attached to the door at 52 represents a catch to hold theknuckle joint, 49 when door is open.

In Fig. 'l is shown a temperature controlled sealed compartment 53 forbutter storage, this compartment being separated from the foodcompartment by door 54 hinged at 55. Also, in Fig. '7, a lamp 56 isshown with its reflector 51 housed into the inner shell of the foodcompartment.

As already stated, an important object of my invention is to provide afood compartment of my refrigerator with circular walls in which revolvecircular shelves 22. To permit of easy revolution and support andcentering of the shelving, I provide a roller arrangement generallydesignated by 22. A preferred form of rollerconstruction is shown byFigs. 3, 4 and 5 in which 60 represents a hori- 1 vertical rollers 68.The housing 8! has an integral pin 61 directed downwardly at an angle,which pins of a plurality of roller constructions 23 when inserted inopenings of the vertical strips 24, support the outer edge of shelves 22and thus permit them to be easily and safely revolved.

A modification of supporting roller construction is shown by Figs. 8, 9and 10. In these figures vertical rollers are omitted, there being onlya horizontal roller having a flange 68 against which the outer edge ofthe shelves contact. With this type of roller construction there is asupporting portion 69 for the roller, this portion having an integraldownwardly'projecting pin 61 which cooperates with openings in verticalstrips 24 for the same purpose as pin 61 of Figs. 3, 4 and 5.

Insulation throughout the construction is designated by Hi.

From the preceding description it will be evident that I have provided arefrigerator construction of exceedingly high efficiency and simplicityin which, by means of the revolving shelves, the necessity of the userof removing food from the front of the ordinary stationary shelves toobtain the desired food in the rear of the shelves. is eliminated.Moreover, by the use of the revolving shelves of my.invention there isno bindingof the shelves as is the case of the pull out type of shelves.In addition, the revolving shelves permit all food located thereon to bevisible at a time when a particular food is needed. It will also be seenthat my novel refrigerator construction permits it to lie flush againsta wall, thus eliminating inaccessible dust accumulation.

Also, through employment of a rectangular cabinet with the revolvingshelf arrangement, rear corner ventilating flues are provided for thcompressor compartment.

Another advantage of my refrigerator construction is the location of theice cube making compartment beneath the food storage compartment.

iii

zontal roller journaled upon bearing 6!, there In thus locating the icecube making compartment no spillage is permitted to fall into the foodcompartment at a time when defrosting takes place or otherwise.

A further advantage of my construction is the provision of gutters anddrains for the food storage compartment and frozen food compartment,thug eliminating the use of drip pans commonly use An additionaladvantage of myconstruction is the location of the gaskets upon therefrigerator housing as distinguished from being located upon the doorsthemselves. In placing the gaskets as heretofore described they are oiitof the way of the hand of the user of the refrigerator and,consequently, cannot be affected by such contact,

I have herein shown and described what I now consider to be a preferredmanner of carrying out my invention but the same is for illustrativepurposes only and I contemplate all changes and modifications that comewithin the scope of the claims appended hereto.
